Whether you are a researcher from academia or industry, engineer, or sustainability enthusiast, this webinar offers a unique opportunity to explore innovative approaches toward building a greener, more resilient future for generations to come.

Welcome Message by Dr. Mohamed M. Shehata:

Welcome to our groundbreaking webinar, where we will embark on a journey through the dynamic realm of silicon solar-cell technology!

We invite you to contribute to this Special Issue dedicated to exploring the latest innovations in silicon solar-cell technology. As the world embraces sustainable energy solutions, silicon-based solar cells stand as pillars of reliability and scalability, offering promising avenues for harnessing solar energy.

Throughout this Special Issue, we aim to uncover a plethora of topics, from the enhancement of ingots and wafers to the exploration of advanced cell architectures such as silicon heterojunctions (SHJs) and Tunnel Oxide Passivated Contact (TOPCon). We seek to delve into the intricacies of defect engineering, impurity gettering, and long-term performance reliability, all crucial elements in optimizing the efficiency and durability of silicon solar cells.

Moreover, we eagerly anticipate contributions relating to the burgeoning field of tandem solar cells, where perovskite materials are integrated with silicon to unlock unprecedented potential efficiency. Additionally, we encourage discussions on sustainable practices for managing the end-of-life phase of PV modules, underlining our commitment to circular economy principles within the renewable energy landscape.

As we convene to exchange insights, expertise, and discoveries, we invite researchers, academics, and industry professionals alike to join us in shaping the future of silicon solar-cell technology. Together, let us push the boundaries of innovation, propel sustainable energy solutions, and pave the way towards a brighter, greener future for generations to come.
